An efficient and mild catalytic deallylation method of aryl allyl ethers is developed, with commercially available Ni(COD) as catalyst precursor, simple substituted bipyridine as ligand and air-stable hydrosilanes. The process is compatible with a variety of functional groups and the desired phenol products can be obtained with excellent yields and selectivity. Besides, by detection or isolation of
以市售Ni(COD)为催化剂前驱体、简单取代联吡啶为配体和空气稳定的氢硅烷,开发了一种高效、温和的芳基烯丙基醚催化脱烯丙基化方法。该工艺与多种官能团兼容,并且能够以优异的产率和选择性获得所需的苯酚产品。此外,通过检测或分离关键中间体,机制研究证实脱烯丙基化经历了-烯丙基镍中间体途径。
